TYPE-WRITING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 439,847, dated November4, 1890.

Application filed July 1, 1889. Serial No. 316,173. (No model.)

To all whom it may concern.-

Be it known thatl, WALTER M. REASON, a citizen of the United States,residing at Caro, in the county of Tuscola and State of Michigan, haveinvented certain new and useful Improvements in Type-Writing Machines,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to new and useful improvements in type-writingmachines.

The invention relates to that class of typewriters wherein the type areattached to keys adapted to be struck by the operator, the paper beingsecured upon a roller attached to a carriage which moves across thetype-receptacle a proper distance as each key is struck to bring theletters in proper relation to each other. The carriage is then withdrawnto commence a new line, and at the same time the roller carrying thepaper is rotated to bring an unprinted portion of the paper intoposition for such new line.

The invention consists in the peculiar construction of the device forreturning the carriage to its initial position and forrotating theroller automatically to feed the paper to anew space by thesame-operation, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure l-is a planview of a type-writer embodying my invention. Fig. 2

is a section on line X X in Fig. 1. Fig. 3 is an end elevation. Fig. 4is a cross-section through the carriage on line Y Y. Fig. 5 is anelevation of my line-spacing device as applied to a different style ofmachine, and Fig. 6 is an elevation at right angles to Fig. 5.

A is the frame of the machine. B are the keys supported upon the leversB, having suitable connection with the type-arms 0, adapted to strikethe lower side of the roller D, which is journaled in the carriage E.This carriage is provided at the front with the roller E, resting uponthe frame of the machine, and at the rear with the grooved rollers F,which bear upon the rod F. F are bearings formed in the rear of thecarriage, through which the rod F passes. In these hearings is securedthe sleeve F upon which is pivoted against the roller D.

the ratchet-bar G, the teeth of which engage with a suitable dog, havingconnections with the key-levers to allow the carriage to move the spaceof one of the teeth forward as each key is struck. A friction-roller Gis secured in the rear of the roller D, and suitable elastic straps Dare used to hold the paper firmly G is a stop adjustably secured uponthe rod F, which arrests the backward movement of the carriage at anydesired point to limit the length of the line. These parts are all ofknown construction and as now in use, except as hereinafter set forth.

My invention is shown attached to this machine, and consists of theshaft I, (having the crank I pivotally secured in the frame projectingwith its forward end in proximity to the keys B, this forward end beingprovided with a finger-piece I, the rear end having the upwardl y-projectin g rocking lever J, on which is secured the segmental circularbearing J, provided upon its upper face with the groove J. At one end ofthis circular bearing is secured a strap or string K, which passesthrough an aperture K in the top of the machine, passes underfriction-arm L, which is secured to the rear end of the carriage-frame,as shown in Fig. 4., and extends and engages into theforwardly-projecting arm M of the ratchet-bar G, all so arranged thatwhen the operator presses down upon the finger-piece I the shaft I willbe rotated, thereby turning the rocker-arm J and the circular bearing J,which in turn will communicate motion to the string, the first action ofwhich will bring downward the forward extension M of the ratchet-bar tothrow it out of engagement with the dog and be held thereby in itsadjusted position. It is evident that in this way the carriage may bewithdrawn to any desired point by simply pressing down upon thefinger-piece. The circular bearing gives the same direction to the pullupon the string at all points of its motion, thereby preventing anyundue friction of the string on the sides of the aperture. The circularbearing also allows of a shorter movement of the crank to produce thenecessary movement of the carriage than if the end of the cord wereattached directly to the end of the rocker-arm J. The groove keeps thecord in its position at all points of the movement. g I H The end of theroller D is provided with a ratchet-wheel N, with the teeth of which thespring-pawl N engages. This pawl is pivotally secured upon thefeed-lever O, which is pivoted to the carriage-frame and extendsrearwardly some little distance.

0 is a spring to hold the ratchet-wheel from turning, and O" is a leverengaging in suitable shoulders on the feed-lever to adjust the movementof the paper more or less.

Q is a curved arm, secured, preferably, upon the stop G and preferablyintegral therewith. The lower part of the arm extends rear wardlyparallel with the rod F, The upper end extends upwardly, forming anincline Q in the'path of the feed-lever 0, all so arranged that as thecarriage is brought toward its initial position the lever O strikes'theincline Q and is depressed, thereby turning the roller D by means of theconnections described. As soon as the carriage moves along, so that thelever O is out from under the incline Q, the spring R again raises thefeed-lever ready for the next operation.

S is a spring, secured at one end to the frame and at the other end tothe rocker-arm J to hold the weight of the crank I and rocker arm J andprevent them from being borne by the cord or strap, therebyadding to theload of the carriage. I

The rod F is pivotallysecured in its bearings and is provided withsquare shoulders,

so that when the carriage is turned back it also turns the stop G andarm Q, being secured thereto, turns also, so that the relation betweenthe carriage and the arm Q is the same at all times. In this way myattachme,nt forms no obstacle to the use of the machine in the usualway.-

T is a lever, (shown in dotted lines in Fig. 2,) attached to the shaftI, having a suitable wire or cord connection T, which may be attached toany form of treadle to withdraw the carriage by a motion of the foot.

In Figs. 5 and 6 is shown my improvement attached to what is known asthe F Oaligraph type-writer, the arm Q being attached back of thecarriage and made adjustable in the frame, so arranged that in tippingback the machine the lever O is lowered out of contact, and in this waydoes not interfere with the free turning back of the carriage and rollerto examine the printing. By this arrangement it is evident that theoperator may move the carriage backward toward its initial position anydistance without turning the roller, except in the event that thecarriage is brought back to commence a new line. This is frequentlydesired to correct errors, to make interlineations, &c., and in thepresent state of the art the devices in use rotate the paper-rollerfirst and then lift the rack-bar out of engagement with the dog to allowthe operator to move the carriage.

In the machine of the type shown in Figs. 5 and 6 the rack-bar is notlifted out of engagement with the dog, and in that case the cord wouldneed to be simply attached to the machine, not requiring the use of thefrictionarm L.

What I claim as my invention is- 1. In a type-writer, a device forwithdrawing the paper-carryin g carriage, consisting of a shaftjournaled in and extending across the frame having a crank for actuatingthe same, a rocker-arm on said shaft, a segmental circular bearin grigidly secured on said arm, and a cord or strap attached at one end tosaid rocker=arm and at the other end to the carriage, substantially asdescribed.

2. In combination with a type-writer, a device for withdrawing thepaper-carrying car- ;riage, consisting of a shaft journaled in the frameof the machine having a crank for actujating said shaft, a rocker-arm onsaid shaft,

a segmental circularbearin g on said arm, and a cord attached at one endto said circular bearing and at the other end to the carriage,substantially as described.

3. In a type-writer, the combination of the following elements: a frame,a carriage adapted to move on a shaft upon said frame and carrying apaper-feed roll, means for withdrawing said carriage to its initialposition, a movable stop upon said shaft. an upwardly and forwardlyinclined arm attached to said stop, and a device for rotating said rollhaving a lever arranged to impinge against said incline when thecarriage is withdrawn, Whereby the feed-roll is rotated, substantiallyas described.

at. In a type-Writer, the combination of the following elements: aframe, a carriage adapted to move on said frame, a ratchet-bar pivotallyconnected to said carriage and having the forward extension M, thefriction-bar L, and a cord or strap passing under said frictionbar andsecured to the extension M at one end and at the other end secured to asegmental circular bearing secured to a rockerbar and shaft, having acrank by which to actuate the carriage, substantially'as described.

, In testimony whereof I aflix my signature, in presence of twowitnesses, this 31st day of May, 1889.
